WILLIAM H. BAUGHMAN', OF BAY CITY, MICHIGAN.

BECEPTACLE.

I Specification of Letters Patent.

Patented July 16, 1918.

Application filed June 19, 1915. Serial No. 35,024.

To all whom it may concern: I Be it known that I, \VILLIAM H. BAUGH-MAN, a citizen of the United States of America, residing at Bay City, inthe county of Bay and State of Michigan, have invented certain new anduseful Improvements in Receptacles; and I do hereby declare thefollowing to be a full, clear. and exact description of the invention,such as will enable others skilled in the art to which it upper-rains tomake and use the same.

This invention relates to a construction of receptacles of especial usein connection with receptacles to contain liquids or articles of food ata temperature above that of the surrounding atmosphere. It is the objectand purpose of this invention to provide a con struction which ispractically proof against loss of heat through the outer walls thereof.Various other objects and purposes consisting of novel constructions andarrangements of parts will be apparent as understanding is had of thefollowing description, reference being had to the accompanying drawings,in which: i

Figure 1 is a side elevation of a receptacle embodying my invention.

Fig. 2 is a. vertical section on the line 2-2 of Fig. 3.

Fig. 3 is a plan view with a part of the receptacle top broken away.

Fig. l is a transverse section taken through the receptacle top, theintermediate plate being removed.

Fig. 5 is a fragmentary side elevation of the reinforcing plate locatedbetween the walls of the receptacle and the top thereof; and

Fig. 6 is a. section on the line 6--6 of Fig. 5.

Like reference characters refer to like parts throughout the severalviews of the drawing.

In the construction shown an open topped receptacle member 1 is providedhaving a base 1". Within, this member a smaller member 2 having asimilar base 2 is positioned the walls of said members and the basesthereof being spaced a distance apart. At their upper edgesthereceptacles are connected by an annular section 3 which may be securedthereto in any suitable mannor. a space is provided which is entirelyinclosed by said members; and it is designed that the air shall beexhausted from this Between members 1, 2, 1", 2 and 3,

space, it being then sealed against any further entrance of air. Ears lsecured to the outer member 1 at diametrically opposed points carry abail 5 equipped with the usual handle 6 whereby the device as a wholemay be readily carried. To reinforcethe side walls of members .l and Q aplate 7 interposed therebetwcen and similarly a plate 8 is interposedbetween the bases 1 and 2. These plates have struck therefrom at aplurality of points triangular tabs 9 which, extending in bothdirections, hear at their pointed ends against members 1. 2, l and 9" aswill be readily understood from reference to Fig. 3. Plates 7 and 8 arelocated between the said members previous to their connection togetherand before the air has been exhausted from the space inclosed thereby.It will be apparent that the outwardly extending tabs 9 serve to resistthe tendency to collapse of the members under the air pressure when. theair has been exhausted from the said space. Also the pointed ends oftabs 9 resting a ainst members 1, 2, 1 and 2 furnish no appreciableconta ct surface for the conduction of heat to the outer member 1 fromthe inner space surrounded by member 2 and thence to the outsideatmosphere; while on account of the vacuum produced between said membersthere will be no passage of the heat through air contact between saidmembers.

The top to the receptacle is formed in a similar manner, consisting ofupper and lower plates 10 and 11 spaced apart with the space betweenthem inclosed by an outer ring 12. A plate 13 provided with triangulartabs 14 similar to the tabs 9 is interposed between the said plates andthe air exhaustcd from the space inclosed by them. This cover is appliedto the open topped receptacle, it having on its under side 11 an annularflange l1 which fits tightly within the member 2 as shown in Fig. '2.

A receptacle adapted to contain liquid is shown at 15 secured to theunderside of the top. The contents of the receptacle may be withdrawnthrough the passage 16 formed in the top and which may be normallyclosed by a cork 17. its usual in constru ...ions of similar nature, acup 18 is detachably connected over an annular ring 19 projectingupwardly from the upper side 10 of the cover. A. receptacle of thisconstruction may have liquid or articles of food introduced thereinwhile at a temperature far above normal atmospheric conditions, theliquid being retained in the part 15 and articles of food of solidnature below said part. By reason of the construction outlined, heatcannot escape through the walls or the top. of the receptacle but willbe retained for a long time.

The construction described is very cheaply and economically produced ata comparatiyely low cost. Various modifications in minor detail may beresorted to without departing from the invention which is defined in theappended claim and all modifications in structure falling within thescope of said claim are to be considered as comprehended within myinvention.

I claim In combination, a receptacle, a cover for the receptacleincluding upper and lower plates spaced apart, a ring inclosing thespace between the plates at their edges, a flange pro1ect1ng from thelower plate adapted to be inserted into and bear against the inner sideof the receptacle, heat passage prevention. means interposed between theupper and lower plates, a receptacle depending from the lower plateinside the flange, an outlet thereto extending through both plates, aclosure for the outlet, and an up- -wardly pro ecting flange surroundingsaid Copies of this patent may be obtained for five cents each, byaddressing the Commissioner of Patents.
